I can’t add much to what others have said, except to agree that the Bose Model II is the best vocal PA I’ve ever owned. Coverage was great, with lots of compliments. However, I’ve convinced myself that backing tracks in stereo sound better----especially for arranger playing, guitar, etc... So, I sold the Bose and got a stereo mixer with powered speakers. If Bose ever figures out how to do what they do in stereo, I’m sure I’ll return.
Oh it's easy to do, you just buy two of them!

I had two of the original L1's, but only once did I need anything approaching that much power. It was outdoors at a large stock car race track.
I then bought two Compacts and after about a year of using them on everything, I sold both of the big ones. I simply don't play venues that require that much output.
I'm a stereo nut also, so I always take both Compacts, even though volume-wise they aren't needed.
The rig that Henni would probably need would cost at least $4,000, for two L1s and a couple of bass bins on each side.
Two Compacts run about $1600 or so, but I'm worth it!
